ASTM A182 F347 Flanges Manufacturer & Supplier in India

Hi-Tech Engineering is a trusted supplier of ASTM A182 F347 stainless steel flanges for industrial piping systems, chemical processing plants, refineries, power generation facilities, and high-temperature process applications. ASTM A182 F347 is a niobium-stabilized austenitic stainless steel grade specifically developed to provide improved resistance to intergranular corrosion after welding and exposure to elevated temperatures.

ASTM A182 F347 flanges are commonly used in refineries, petrochemical plants, fertilizer facilities, heat exchangers, power plants, and high-temperature piping systems where resistance to carbide precipitation and intergranular corrosion is important. The addition of niobium helps stabilize the material and makes it suitable for welded applications operating at elevated temperatures.

These flanges offer excellent weldability, good mechanical strength, oxidation resistance, and dependable performance in high-temperature service conditions. ASTM A182 F347 flanges are available in Raised Face (RF), Ring Type Joint (RTJ), and Flat Face (FF) configurations to suit various piping and pressure system requirements.

At Hi-Tech Engineering, we can supply ASTM A182 F347 flanges in pressure ratings from Class 150 to Class 2500 with complete material traceability and inspection documentation. Depending on project requirements, flanges can be supplied in rough machined, semi-finished, or fully machined condition. Material Test Certificates (MTC), PMI testing, dimensional inspection reports, and third-party inspection services can also be provided upon request.

With a focus on quality, timely delivery, and competitive pricing, we serve customers across India as well as export markets including the UAE, Saudi Arabia, Oman, Qatar, Kuwait, Bahrain, and other international destinations.

We also supply other forged flange materials including ASTM A105 Carbon Steel Flanges, ASTM A182 F316 Flanges, Weld Neck Flanges, Blind Flanges, Slip On Flanges, and Threaded Flanges for industrial piping applications.
